STOP-MOTION FOR RlBBON-LOOMS.

SPECIFICATION forming part of Letters Patent No. 699,112, dated April 29, 1902. Application filed November 1, I901. Serial No. 80,739. (No model.)

To all whom, it may concern.

Be it known that I, WILLIAM I. POST, a citizen of the United States, residing in Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Stop-Motions for Ribbon-' Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form apart of this specification.

This invention relates to looms; and it has reference particularly to ribbon-looms. In this class of looms damage often occurs to the goods being woven because by an irregularity in;the operation of the parts the shuttles stand in the shed interposed between the reeds and the webs when the batten moves forward to beat up the wefts. What is known as a smash-protector? is usually madeLuse of to prevent damage oceurringvto the goods; but this expedient is not perfectly satisfactory-in fact, it is a hi g'hly-im'practical means for overcoming the difficulty, since so long as a shuttle is interposed between the reed and the web and the batten-continues under power to beat up as usual to the full extent it is impossible to avoid entirely the possibility of some damage resulting.

The object of this invention, therefore, is to provide means whereby should the shuttles stand between the reeds and the webs at any time while the beating up isin progress the power will be immediately thrown off and the loom at once stopped.

My invention will be found fully illustrated in the accompanying drawings, wherein- Figure 1 is a fron'tview of enough of the end portion of a loom to properly show my invention in position thereon.

3 is a top plan view of what is seen in Fig. 1.

Fig. 4: is an enlarged top plan View of the Fig. 2 is a sec-v tional view of the loom, taken just to theright of my mechanism as it is seen in Fig. 1. Fig.

In said drawings, a and b designate, respectively, the breast-beam and the batten, arranged as usual in the frame 0. 1

d denotes the shuttle-blocks, e the shuttles, f the rack, g the'shuttle-driving pinions, and h the reeds, and i is the cloth-beam, all arranged as usual on the batten.

j and 7c are bearing-brackets in which is journaled on the batten a shaft Z, said shaft penetrating the endshuttle-block and carrying a pinion m, which engages the teeth of the rack f. The front end of this shaft also carries another pinion n, which engages with a gear 0, that is journaled on a bracket 19, secured to the face of the batten. This gear is provided with a crank q.

In brackets r, secured to the front face of the batten b, is adapted to slide arod s. This rod is adapted to be operatedfrom the crank q through the medium of a connecting-rod 25, whose ends are pivoted on studs u and u on the rod 8 and the crank q, and which is formed in two parts ad justably connected by bolts to, which penetrate slots win one of the 1 parts, so as to afford adjustment. The rod 3 carries a thimble y, into which is screwed a socket z, carrying a bu Eer 1, which is pressed 'normally outwardly by a spring 2 in said socket, its movement being limited by a pin 3, which it carries and which works in a slot 4 in said socket.

5 designates a block which is arranged for movement slightly inwardly andout'wardly with reference to the breast-beam, in which itis held by means of bolts 6. In order to permit of the movement of the block referred to, itwill be understood that the nuts on the 0, crank q, connecting-rod t, and rod 8,) the buffer will stand beside the block and at the vleft thereof, as shown in dotted lines in Fig.

5. Its normal motion is therefore relatively to the other parts an oblique one. In order to insure the buffers clearing the block,a section thereof is removed, as at 8. (See Fig. 5.) If there is an irregularity in the action of the parts, so that the shuttles are not entirely withdrawn from between the reeds and the webs when the batten heats up, the buffer 1 will contact with the block 5 and press it toward the breast-beam.

9 designates brackets in which is arranged a slide-rod 10, which is normally pressed to the left by a spring 11, interposed between a pin 12 on said rod and one of the brackets. A pin 13 on the breast-beam engages a recess 14 in the rod and normally holds it against the tension of its spring in the position shown in Fig. 5; but the rod has a slight lateral movement in its brackets, so that if it is displaced laterally, so as to disengage the pin 13 from its recess, the spring will immediately throw the rod to the left. This displace ment is adapted to be efltected by pins 15, loosely arranged in the breast-beam and interposed between the block 5 and the rod 10.

16 denotes the usual hand-rail for working through the lever 17 the belt-shifter 18. On this hand-rail and opposite the end of the rod 10 is mounted a lug 19. Thus when the rod 10 is released it engages the lug and throws the rod 16 to the left, thus efiecting the shifting of the belt 20 from the fast pulley 21 to the loose pulley 22.

In setting the mechanism when the rail 16 is thrown manually to the right in order to shift the belt onto the fast pulley the rod 10 is simply pushed toward the breast-beam, when its recess 14 coincides with the pin 13, thus resulting in setting the block 5 in its operative position.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In aloom, the combination of a support, a movable spring-pressed part carried by said support and arranged parallel with the batten, means for securing said part to the support in its retracted position, said part being also movable laterally with reference to its direction of movement under pressure by the spring to disengage the securing means, and means for moving said part laterally,sitbstantially as described.

2. In a loom, the combination of a movable part of the power-controlling mechanism of the loom arranged parallel with the batten, the breast-beam, another part adapted to engage said first-named part to actuate the same, a spring normally pressing said last-named part toward the first-named part, means for securing said last-named part to the breastbeam in its retracted position, said last-named part being also movable laterally to disengage the securing means, and means for moving said last-named part laterally, substantially as described.

3. In a loom, the combination, with the batten, a suitable support and a spring-pressed movable part arranged parallel with the battracted position, said part being movable laterally with reference to its direction of movement under pressure by the spring to disengage the securing means, cooperative parts, one of said parts being carried by said batten and adapted to engage the other to move the same, operative connecting means between said first-named cooperative part and said member adapted to move said part out of alinement with the other cooperative part, and operative connecting means also between said other cooperative part and said part of the power-controlling mechanism, substantially as described.

4. In a loom, the combination, with a stationary part of the loom, of the power-controlling mechanism of the loom,a slide-rod mounted in said part and adapted to engage said mechanism to actuate the same, a spring normally pressing said slide rod toward said mechanism, means for securing said slide-rod in its retracted position, said slide-rod being movable laterally to elfect its release and permit the spring to move the same, a block movably arranged in said part, pins interposed between said block and said slide-rod, and means for moving said block, substantially as described.

5. In a loom, the combination, with the batten and with the power-controlling mechanism of the loom comprising a movable part, of the shuttle-driving rack arranged on said batten, a reciprocating member also mounted on said batten, and operative connecting means between said rack and said member adapted to transmit the movement of the rackbar coincidentally to said member, said member being movable into and out of contacting opposition to said part, substantially as described.

6. In a loom, the combination, with the batten and with the power-controlling mechanism of the loom comprising a movable part,

' of the shuttle-driving rack arranged on said 5 batten, a reciprocating member also mounted on said batten, and operative connecting means between said rack and said member adapted to transmit the movement of the rackbar coincidentally to said member and comprising gearing engaging said rack-bar and a connecting-rod between said member and the gearing, said member'being movable into and out of contacting opposition to said part, substantially as described. I

In testimony that I claim the foregoing I have hereunto set my hand this 31st day of October, 1901.
